[ka-Map-users] deactivate cache system

[Emilio Ponce]

Ok Lorenzo, here's a little background about my work:

The user has the browser's screen divided in two parts. at the left has a
table with different variables, one on each column (all are alphanumeric
data). At the right the map.
I've developed a java class that depending on the column of this table the
user choose (population, surface, deaths ...),  rewrites the mapfile. That
means that the layer and its geometries are always the same, but not the
colours, that change in function of the values of the variable represented.
The problem is that with the cache I can represent the first variable in the
map without problems, but at this point the map becomes static. When I try
to represent the second variable, I see the map of the first, I think is
normal because the layer is exactly the same (name etc) except by the
colours that are different.
If I turn off the cache, the mapfile is forced to rewrite the layer with new
images, and it seems to be a solution, maybe not the best :).. in fact,
there's another way forcing ka-map in order to rewrite the images of the
layer??

Sorry for this large e-mail, and thanks everyone!
